Patent abstract
Solutions comprising a sodium silicate waterglass having a modulus of less than 3 and at least 8% by weight of an organic polyhydroxy compound such as glycerol are useful in the production of interlayers used in fire resistant glass laminates. The solutions are dried on a flat surface such as glass to produce a clear intumescent interlayer having improved impact resistance. The dried interlayer may be removed from the surface in the form of an elastomeric material which may also be used as an interlayer in a fire resistant glazing.
